When dieters embark on a low calorie diet plan, a major concern is the body’s inability to maintain metabolic balance. Because dieting, like the Diet Doc hCG diet plans, most often entails consuming fewer calories, very often this change will cause the body to enter the metabolic state known as starvation mode. Once the body attempts to protect weight loss by slowing the rate of energy consumption, losing weight is virtually impossible. Unfortunately, this is an archaic protection mechanism from the beginnings of human history, unnecessary in the modern, food laden world. The problem with starvation mode is that even if a person is overweight by 100 pounds or more, the body will still think that it is starving during lowered caloric intake, protecting this abundance of extra weight and making dieting impossible.
